Nothing real about Jay-Z or Kanye West - everything they have done in the last decade or so has been carefully weighted with the market in mind. That's not real art.
Jay uses the hip hop market. Kanye helps create it. and mainstream artists get hated on so much, but that career is harder than an underground artists. underground artist, with total creative control, do what they want, what is natural, what comes out, as far as whats on paper and on wax. a major artist on the other hand has to create what he's told. swimming upstream, if you will. and the outcome is the same as an underground artists. he will create a song that some people will suck, and some people will say sucked.
the underground has more wack rappers, per capita.
